DISPENSING AND MEASURING PUMP.

To aZZ whom it may concern:

Be it known that l, FRANK E. DAYTON, a

citizen of the United States, residing at Los Angeles, in the county of Los Angeles and- State of California, have invented new and useful. Improvements in Dispensing and Measuring iunips, of which the following is a specification.

This invention relates to dispensing and measuring pumps, and more particularly to improvements in housings for such pumps of thetype which is stationed out of doors and is thus sub ected ,to the elements and tampering with by unauthorized person s, the

primary oo'ject of the invention being the provisien'of a housing which is constructed so that access to the mechanism which it houses, for-the purposes .of inspection or repair thereof, is permitted readily, and without requiring disassembling of the pump.

In the majority of dispensing apparatus, dispensing and measuring pumps which are stationed out of doors and have casings or housings protecting the pump mechanism, the housings or casings are constructed in such a manner that it is necessary to completely disassemble the pump,'and in the majority of 'instances to remove the pump from its supporting base,

in order to gain access to the pump mechanism or parts for the purpose of lnspection, repair or renewal of parts thereof. Therefore the repair, inspection or renewal of" parts of pump mechanism in dispensing apparatus of this type, is annoying, consumes a great deal of time, requires-a great deal of lahorand is generally otherwise objectionable. My invention entirely overcomes the alcove-noted objections in a reliable, economical and facile manner. To this end my invention consists in the provision of a- 3 I sectional housing, the lower or base section or which instead of belng stat1ouary,'as is i: generally the case, is movable and can be elevated into position to allow access to the pump mechanism which it houses when in down position; and, my invention further consists in the particular cooperation and association of this movable lower or base section of the housing, with the upper sec tion of the housing, which upper section is movable so that it will serve when in. up po-' siticn to house and protect the upper or operating mechanism for the pump, and

when in down position will permit access to said upper or pump operating mechanism.

With the above and other objects in View,

in elevation of a dispensingapparatus constructed in accordance 'Withthe invention showing the apparatus in locked position; Fig. 2 is a side elevation of the pump broken away and-partly in section, iliusmating the movable lower section of the housing in elevated position so as to permit access to the pumpelements;

Fig. 3 is aside elevation of the pump broken away at one corner and showing it as it would appear ready-for service; i

Referring particularly to the drawing forming a part of this application and in which like parts are designated by lilr'e'char--v actors, throughout the several views, 1 generally designates the housing forming the Subject-matter of this invention, and 2 the measuring and dispensing apparatus which is disposed within the housing 1 The dis penslng' apparatus 2 comprises a measuring cylinder 3, a filter 4 operatively associated therewith, a service pipe 5 connected with the filter, pump mechanism 6 operative-1y associated with the cylinder 3, a liquid sup ply pipe 7 connected with thecylinder 3, a.

.9 and having suitable illuminating means,

not shown therein. The frame 8 comprises vertical standards 11 which-at their lower ends are connected with a base casting l2, and at their upper ends with the dome 9, said upper ends being screwthreadedv as; at 13.

and turned into screw-threaded openings I L ards 11 a pump mechanism supporting cast ing 15 is located, said casting being provided with openings 16 through which thestandformed in the dome 9. Intermediateand approximately central of the ends of the standards 11 extend. The casting 15 rests upon the upper ends of tubular standards 17 which surround and receive the standards 11, the lower ends of said tubular standards I '5 17 being disposed within the counter-bored portions 18 of the base casting 12. The standards 11 extend through the base casting 12 and have nuts 19 turned on their lower ends. Pins 20. are inserted transversely through the standards 11. and are adapted to engage the upper side of the casting 15 so that when the nuts 19 are screwed up upon thestandards'll said pins 20 will tend to force the casting 15 into firm engagement with the upper ends of the standards 17. In addition to the standaids 11 and 17 there is provided a supporting rod and tube 21 and 22, respectively. The rod 21 is fixedly engaged with the casting 15 and extends through the base casting 12 as do the standards 11. Inthis connectionit will be noted pending flange 23 formed at the periphery of the base. A nut 24: is turned upon the.

lower end of the rod 21, and the tube 22 surrounds and receives the rod 21, such tube serving to support the casting- 15 as do the tubular standards 17.

The measuring cylinder 3 is suitably connected with and depends from the casting 15 and the filter 4: is likewise connected with the casting. As a means for supporting the cylinder there areprovided series of rods 25 which arefixedly secured to the casting 15 and extend downwardly therefrom along the outer side of the cylinder to a point below the lower end of the latter. A spider supporting member 26 is connected with the lower-ends of the rods 25 and rests against the lower end of the cylinder, there being provided nuts 27 turned upon the screwthreaded ends 28 of the rods 25 and into engagement. with the spider 26 so as to hold the latter in position, and to likewise provide for the ready removal of the spider and cylinder for the purpose of inspection, repair or renewal of parts thereof, or of 5 parts operatively associated therewith. .An

easily operable couplingmember 29 is provided for connecting the supply pipe 7, with the casting 30 forming the lower part of the cylinder 3. Utilization of this type of coupling provides for an expeditious assembling or disassembling of the pump. There is provided a head casting 31 which is connected with the casting 15 and together with said casting supports the mechanism 2' for operating the pump, such mechanism including a rack bar piston rod 32 operatively as- 1 sociated with the cylinder 3 and capacity regulating means generally designated 33. It is not thought necessary to specifically and in detail describe the pump operating -with the exception of the can i .coiiperate with the stop to limit newness mechanism which is or conventional form, ty control means The means co rises rotatably mounted verticaily disposed rod which is rotatahiy iournaled as at its "2? upper end within a web portion 36 of the head casting 31., and at its lower on is rotatably mounted within a socket for formed in the casting 15. ii. spring mounted within the socket S7 and is posed between t is lower end of the r and the socket 3 so as o provide for tionally holding the rod .n adjusted. tion. Stop lugs 39 and d0 are determined points upon the rod 34-, tend in opposite directions horieontaiiy from said rod, there being pins {sill that are inserted transversely through the lugsand rod to hold the lugs in place. stop siement orlug 42 is fixed to the rack bar 32 and adapted for cooperation with either the lugs 39 or 4-0. As shown Fig. i the drawing the lug 39 is disposed in an out of the way position and the lug so is disposed in operative position so that when the piston rod rack bar 32 has been moved a pie determined distance so as to cause a predetermined amount or" liquid to enter the cylinder the lug 4:2 thereon will en adjusting screw 43- which is carriez lug 4&0, and the operation, that is, thor movement of the rack bar is p vented. A. screw L4 is provided for the 39, said screws 43 and at providing for desired regulation of dispensation of liquir. operated upon by the pump. By turning he 1 rod 8d the lug 39 may be brought into and the lug 4.0 18 then disposed of-tlie way position. The ug in ment of the piston rod and operati pump.

The housin 1 for the apparati' fore described, comprises a lower the casting 15 preferably iits snuglywiitihn the upper end of the section 4:5, said upper end terminating preferably flush with the upper surface of the casting. "in this connection it will be noted that the casting at its periphery is disposed beyond the standards 17 and 22, thus the housing sew tion 45 is eircumierentially spaced from frame 8, that is, the standards 1? and-22.

The upper housing section is provided exteriorly near its upper end and upon opposite sides with the handles and with latch bar which is located at and extends above the upper end thereof. This i bar 50 is adapted to coiiperate with a v newness one .46 forming a part of our invention have been used heretofore, but I consider the -movable lower*sec'tion 45 the essence of my invention and in the use of my invention when it is necessary to inspect .the pump piston, not shown, any of the filter parts, not shown, or any ofthe parts or coiiperative parts of the pump, it is only necessary to raise the housing section l5 into the position shown in Fig. '2 of the drawing. When the" housing section 4 5 is thus raised aecess'to the pump parts is readily had, whereas in pumps of the type heretofore, known and now in usethe housing for the lower part. of

the ump mechanism is stationary as mentioned hereinbefore, To hold the housing the parts of my invention may be resorted to when required, without departing from the spirit and scope of the invention as defined.
